Product Description
Fixing hardware, not a CCTV component — but a common ancillary for installers securing mounting plates, junction boxes and trunking to timber during a camera install.

TIMCO Velocity 3.5 × 40mm wood screw with a countersunk head and Pozi drive, finished in yellow zinc plated steel.
Key specs
- Size: 3.5mm diameter × 40mm length
- Head: countersunk — sits flush once driven in
- Drive: Pozi recess — reduces cam-out on a driver or drill
- Finish: yellow zinc plated steel for corrosion resistance
- Material application: timber, chipboard and general wood fixing
On a CCTV job
This screw is for wood-based fixings only — timber, chipboard, stud walls, wooden fascias or shed frames. SOURCE does not cover masonry, brick, block or metal fixing, so don't spec it for those substrates. The 40mm length is described as suited to medium-depth timber fixings, relevant when mounting a bracket plate or cable clip where the screw needs to bite into a joist, batten or backing board without punching through thin ply.
Sourcing check
Countersunk head and Pozi drive mean it should sit flush and accept a standard Pozidriv bit without cam-out during install — useful when fitting multiple brackets on a first-fix run. No claims beyond wood/chipboard suitability are made for this screw.
